C.J. Spiller could see some practice time this week

Fred Jackson, C.J. Spiller both questionable for Week 4

Buffalo Bills running backs C.J. Spiller and Fred Jackson are both listed as questionable for Week 4 against the New England Patriots due to injury. However, head coach Chan Gailey said that both players have a legitimate chance to play on Sunday.

Jackson has remained optimistic that he will be able to suit up and told reporters that the only way he was going to miss the game was going to be if something unexpected happens prior to game time. Earlier this week, Jackson said that he was 70-75 percent certain that he will be playing. He is attempting to return from the LCL sprain sustained in Week 1 against the New York Jets.

In terms of Spiller, it was widely expected that he would be unavailable against the Patriots after suffering an AC joint sprain against the Cleveland Browns in Week 3. However, the back has participated in practice the last two days and it seems as though it will be up to the medical staff to determine whether he plays and, if so, how prominent his role will be.

Running back Tashard Choice is available regardless of the status of Jackson or Spiller.

C.J. Spiller injury update: Bills' RB practices Thursday

C.J. Spiller, the Buffalo Bills dynamic running back, was spotted at Thursday's practice dressed and participating in individual position drills, the team's official website is reporting. Spiller is trying to make a quick recovery from a shoulder injury he suffered during Buffalo's Week 3 victory, 24-14, over the Cleveland Browns. On Wednesday, Spiller only worked on the side with no helmet or pads as the Bills prepare for Sunday's contest with the New England Patriots (1 p.m. on CBS).

Its still unclear if Spiller was limited for the session, as head coach Chan Gailey has yet to speak with the media, but his return to the practice field shows progress.

Before Thursday's practice, Spiller told WGR's Joe Buscaglia he was going to be cautious during his workouts.

"We'll see how it goes. The main thing we don't want to do is rush it," he said. "It's only Week Four, we've got 16 more and plus if we want to get in to the postseason. We'll do it day by day and see what Sunday holds."

Spiller entered Week 3 of the NFL regular season as the league's leading rusher. However, he left Sunday's game early after he awkwardly landed on his shoulder on a screen play that was later nullified by a penalty.

Initially, it was expected Spiller would be out a few weeks, however, the former Clemson Tigers has healed quickly. His return for Sunday is still questionable.

C.J. Spiller injury: Bills RB could practice this week after all

After suffering what appeared to be a serious injury on Sunday against the Cleveland Browns, Buffalo Bills running back C.J. Spiller could be back at practice before the end of the week. Bills head coach Chan Gailey was noncommittal on whether Spiller would be back for sure:

"He's not going to practice today, but we're hoping we'll get him a few reps maybe by the end of the week," said Gailey of Spiller. "I don't know for sure. We'll see."

Spiller suffered a sprained A.C. joint, which is not as serious as the broken collarbone or separated shoulder that many initially thought he suffered. He will still likely miss the Bills' game against the Patriots, but could very well be back in the lineup the next week against the 49ers. The Bills received even more good news on Wednesday, as Fred Jackson returned to practice for the first time since getting hurt Week 1 against the Jets.

C.J. Spiller's Injury Is Sprained AC Joint

Buffalo Bills' running back C.J. Spiller has been diagnosed with a sprained acromioclavicular joint, according to Jason La Canfora of CBS Sports. The recovery period is expected to be one to two weeks.

Spiller sustained the injury in Sunday's 24-14 victory over the Cleveland Browns, when the back was brought to the ground by Browns' safety Usama Young. He was unable to return to action and finished the day with 16 yards on four carries in addition to two receptions for 42 yards and a touchdown.

Head coach Chan Gailey stated that injured back Fred Jackson is expected to return to practice this week after missing time due to an LCL sprain sustained during Week 1 against the New York Jets. Gailey would not speculate as to whether Jackson would be available for Week 4's meeting with the New England Patriots, but did state that he was comfortable starting Tashard Choice.

C.J. Spiller To Have MRI On Injured Shoulder

C.J. Spiller left Sunday's game early with a shoulder injury, and we hadn't gotten an update on the NFL's leading rusher until now.

Bills still gathering information on CJ Spiller's injured shoulder and an MRI is scheduled for Monday

— Jason La Canfora (@JasonLaCanfora) September 23, 2012

Buffalo have now turned to third-string RB Tashard Choice in Spiller's absense, as the team lost starting RB Fred Jackson with an LCL injury in week one. Should Spiller miss significant time it will deal a huge blow to their offense, and to QB Ryan Fitzgerald, who utilized the elusive RB as an effective backfield receiver.

The Bills remain in control on Sunday's game, currently up 24-14 over the Cleveland Browns, but without Spiller their offense is clearly hurting, and they lack a much needed 'big play' ability in their offense. The Bills have turned to Choice, and he has been quite productive totaling 86 yards on 17 carries thus far.

C.J. Spiller Injury: Bills RB Hurts Shoulder Vs. Browns, Will Not Return

After leading the Buffalo Bills to an early lead, running back C.J. Spiller has left Sunday's game against the Cleveland Browns with an apparent shoulder injury. Spiller left the game after landing hard on his shoulder after a hit from safety Usama Young. He will not return, the team announced.

Spiller, the Bills' first round pick in 2010, has powered Buffalo's offense early in the season with Fred Jackson out, but now he may be joining him on the sidelines. It appears that the injury is to his left shoulder, as ESPN's John Clayton notes that Spiller's arm is currently immobile.

Spiller had carried the ball four times for 16 yards prior to his injury. He also caught two passes for 42 yards and a touchdown.
